1992-93 Results of geomorphological and field studies Volcanic Studies Program, Yucca Mountain Project

PDF Version Also Available for Download.

Description

Field mapping and stratigraphic studies were completed of the Black Tank volcanic center, which represents the southwestern most eruptive center in the Cima volcanic field of California. The results of this mapping are presented. Contacts between volcanic units and geomorphic features were field checked, incorporating data from eight field trenches as well as several exposures along Black Tank Wash. Within each of the eight trenches, logs were measured and stratigraphic sections were described. These data indicate that three, temporally separate volcanic eruptions occurred at the Black Tank center. The field evidence for significant time breaks between each stratigraphic unit is ... continued below

The field evidence for significant time breaks between each stratigraphic unit is the presence of soil and pavement-bounded unconformities.
